IMPROVEMENT IN ESOAPEMENTS FOR TIME-PIECES.

TO ALL WHOM IT MAY CONCERN Be it known that l, HERMAN REINECHE, of thecity, county, and State of New York, have invented a new and improvedEscapcment for Time-Pieces; and I do hereby declare that the followingis a full, clear, and. exact description thereof, which will enableothers skilled in the art to make and use the same, reference being hadto the accompanying drawings, forming part of this specification, inwhich- Figure 1 represents a sectional front elevation of thisinvention,

Figure 2 is a side elevation of the same.

Qimilar letters of. reference indicate like parts.

This invention relates to a mechanism which combines the advantages ofthe detached escapement with the lever escapcment, the balance being soarranged that it receives an impulse from the escape-wheel, while itswings in one direction only, being perfectly free from the power of themain-spring during the other halt of its motion, and the impulseproduced by the escape-wheel is transmit-ted to the balance by means ofa lever.

- A represents the escape-wheel, and B the balance, which is mounted onthe arbor or staff a. The-escapewheel has a tendency to revolrc, underthe action of the main-spring, in the direction of the arrow markedthereon in fig. 1, and its teeth act on the pallets p, which projectfrom a bar mounted on the arbor b, the palletp being so sha ed that thesame fits between two succeeding teeth of the escape-wheel, and thatwhen the arbor his turned in the direction of the arrow marked near itin fig. 1, so as to raise the pallet 11, the joint of the tooth of theescape-wheel glides down over. the inclined face of said pallet, and asthe tooth leaves the pallet 10, the next preceding tooth strikes thepallet 10, and causes the pallet to drop again between the teeth to theposition in' which it is shown in fig. 1. The oscillating motion of thearbor 6 is produced by the action of a pin, a, which projects from thehub of the balance; and which acts on a lever, C, that is mounted on thearbor 6. From the end of this lever project two pins, (Z a, and aliftiug-spring,f, bears against the pin e. The

.pin (2 acts ona piu,g, projecting from the hub of the balance, andserves to impart to said balance the required impulses. If thebalanceswings in the direction of the arrow, marked on it in fig. 1, thepin 0 passes the liftingspring f without producing any motion of thelever C, and the pallets are not disengaged from tho escape-wheel; butif the balance returns in the direction opposite the arrow marked on it,the pin 0, on coming in contact with the lifting-spring, causes thelever C and arbor Z) to turn in the direction of the arrow marked nearit in fig. 1, and the palletp rises, allowing the tooth of theescape-wheel to slide down on'its inclined edge. As soon as the toothstrikes the inclinededge of the pallet, the pin (Z is thrown in contact,with the pin 9, in the hub of the balance, and an impulse is given tosaid balance sufiicient to keep up its motion. When the pin a has passedthe lifting-spring, the lever C returns to its original position by theactionof the escape-wheel on the palletp, and the balance, in swingingin the direction of the arrow marked on it in fig. 1,. is relievedentirely of the force of the main-spring, and it has to overcome noobstruction besides the friction, the resistance of the air, and that ofthe liftiIzg-spring. By thishrrangemcnt an escapement is obtained inwhich the impulses imparted to the balance are as near as possibleuniform, and furthermore, during a large part ofits motion, the balanceis entirely relieved of the power of the main-spring, and itsoscillations become isochronim My eseapement'is applicable, with equaladvantage, to a horizontal or to a verticai balance, and itcan be usedfor clockmovements as well as for watches.

What I claim as new, and desire to secure by Letters Patent, ispThepallctsp 31, mounted on the oscillating arbor b, in combination withthe lever G, lifting-springf, pins d e g c, and balance B, allconstructed and operating substantially as and for the purposedescribed.

HERMAN REINECKE.
